And the problem is that check does not work

I "broke" the check when I added support for cross-compiling GHC.

All you need to do is override the default GHC to disable building it for the RISC-V platform such that the check functions as originally intended.

This isn't actually in the build logs, is it? ("Disconnected" in ja_JP locale?)

Rip, openexr failed tests due to 1 test timing out

This unfortunately happens for some packages. Commonly available RISC-V cores can be far slower than the heavily optimised and mature x86 platforms that often set the timings.

You could report the issue upstream, but for now disabling checks is an easy solution. It could even save hours of building if you do it pervasively.

Emulated builds (e.g. via binfmt) also struggle with the problem.

Access to clocks and timings interferes with reproducibility, but they are very difficult system calls to take away.
